Application filed .April 4,

To all @1i/wm I? may concern.'

Be it known that l, Lum lvl. lllons'r, a citizen oil the United States. and resident ol' Milwaukee, in the county or" llilivaulree and S'ilate of lliscousiin have :invented certain .new and useful ,improvements in @if and I do hereby declare that the tolloivng :is a full, clear7 and exact description theieoi".

The invention relates to sitters ot a typo adapted to feed material7 such as flour, through a series of screens.

lt comprises a plurality ot sitter sections each provided with a screen aiidnested in a lower section, agitators operable on the io tation olf' a lznob to stir the material be' D' '.siiitod, and locking devices; ivhereby the sec tions are secured to each other and readily released.

ii. primary object of the invention is the :ready assembly and locking together ot the diverse sitter sections and parts and tic i''acile removal o l the sections ttor cleaniuo. Each of the sections is provided with a bar net joint7 whereby 'it cooperates with oher ftions. rlhe handle has a pair oit :flanges which cooperate with ears on cach section so that thehandle may be readily and conveiiiently slipped into place ivhere it 'will hold the sections iii rigid relationship.

in additional object ot the invention is thc provision of a longitudinal deformation p or. a rod rigid with the handle, the deformation being adapted to grip the ears oi' the sitter sections, thus preventing the handle trom accidentally sliding; with sections and permitting' the carr vif; et Vthe entire sitter about on the handle Without danger oiI release et any of the sections.

fin object ot the `inif'i-fntion is the ci uvciiient association ot screen with its sitter scctioin the section beingl merely crimped to grip a ilange on the screen. y f

Additional objects are simplicity oit ccnstruction and ease of manufacture. The device is, also, thorough in its operation as the portable sections cooperate with the agitat# ing,` spiders to completely remove the undesirable particles from the material si'ftcd.`

lli/*ith the above and other objects in view, which will appearv as the description proceeds, my invention resides in the novel con` struction, combination and arrangement of parts, substantially hereinafter described and more particularly defined by the appended. claims, it being understood that such 1922. Serial No. 549,642.

changes in the precise embodiment of the herein disclosed invention may be made as come Within the scope ofthe claims.

ln the accompanying drawing7 l have .illustrated one complete exan'iple ci the physical embodiment ci the present invention constructed according; to the best mode l have so iar devised for the practical application oi' the principles thereof, andy in which: Figure l is a horizontal section on the line l-l oit Figure 2.

Figure 2 is a side elevation of the invention7 the upper part being` shoivn in vertical central section. i

Figure 3 is a detail oi'i' the lot. l The various sitter sections are of similar shape, but body portion l() of the lovver sections is or slightly different construction :troni body portion ll ot' the topmost' section. `Body portions lO are provided with an Lsliaped deformation adjacent the upper peripheral bead 13 adapted toreceive a boss la on the sleeve 16 ci' the sitter section in'nnediately above. The body portion l() of slightly greater'diaineterthan the sleeve i6 and at 1"? is crimped upwardly to iforin held rigidly in position. rllhis n'ianner ci association oit screen and sitter section is convenient to malte and simple in nature. Troni told it the metal is directed der' Wardly at 2l forming' sleeve l@ which termi-- nales in an inwardly directed bead 22. Body pr tion ll. is not provided with an lsliaped determi lon but terminates in circunrerential bead 28 andy supports Spanner 24 having a central boss through which a v ertical rod 26 is directed, the rod being integral with arm 27 carrying knob 28. The i'odis square in cross section aiid 'passes` through openings in screens which are protected by an eye 29 and a washer 30 held kin position by flange directed outyvardly trom the eye. The eye serves to reinforce the screens at this point, protecting them :from abrading action. agit-eters 32 have ka plurality of arms pr ,vided withy central, longitudinal, downwardly directed deformations 3 4. The agitators are provided with a central opening receiving rod 26 and are protected by an iron reinforcement having a square opening so that the reinforcement and agiicck vone pair ott eer-s titer eno-ther.

tutor fits snugly between rod 26 and on tbe rotation tbereoit7 tbe agitator is moved eensing deformation 34: to scrape along Screen and stir the flour or other materiel Wliieli ie oeing snbjeeted'to tbe sifting operation, The Hour drops from one screen to another and is more thoroughly si'ted es it approaches tbe lowermost sitter section.

Eeeli olf the sitter see-tiene is -provided with a parir of ears 36, the arms of which are do'wmvnrdly directed and receive longitudinal ilai'igee directed inwardly from rod 39 to which bnndle 1-0 is Secured.

n assembling the parte, eeelz ,Glitter eef;- tion .is neetingv in :i lower Si'ter Section, tlie boss l being moved dmvnimrdly end e greged in deformation-l2 by tbe rotation olf sitter see-thine Witli respect to euch other,

' tbe conneetion being` e bayonet joint. The

L36 are tlienelined end rod is moved up by manually gripping handle 40 Aand leng'es ere Slid into oosition engaging; The entire device is 'then in assembled relation. Rod 39 is provided with n longitudinal eorrngation ll 1\vl1iol1 contacts with arms 237 of eers und maintains a tight 'rietionel engagement therewith so that the entire Siiter may be lifted by handle 410 endeairied from place to place.` Rod 26 is assembled with respeot'to the sitter sections by being` merely ythreaded through the openings in boss tlie agitators 32, and eyes 29.
